IMPROVEMENT IN PINCHERS.

Specification forming part of Letters Patent No. 163,277, dated May 11,1875 application filed November 23, 1874.

To all whom it may concern:

Be it known that I, GEORGE H. STRONG, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inPinchers, of which the following is a specification:

The nature of the present invention consists in the jaws of pincherswith a swage, for fitting joints of pipe to each other. A stop or gage,being attached to the jaw of the pinchers, is used to bring the swagealways the same distance on the pipe.

In the drawing, Figure 1 is a longitudinal elevation of my improvementin combinationpinchers; Fig. 2, a broken elevation of the 0pposite sidefrom that shown in Fig. 1; Fig. 3, a section on line m 00, Fig. 2.

A represents one lever of the pinchers, which is provided with atack-claw on the end at O, a can-opener at E F, one side, G, of anutcracker, one part, H, of a swage, and one jaw of the pinchers. Brepresents the other lever, which is pivoted to the lever A at I, andpro vided with a screw-driver at J, the other side K of the nut-cracker,a hammer, L, a wire-cutter, M, and the other 'partN of the swage. Thelevers are also provided with holes 0 0 through their longer ends, forturning off the tops of fruit-cans. The can-opener consists of a sharppoint, E, and a cutter, F, of ordinary construction, and is to be usedby thrusting the point and cutter into a can, and thus using the pointas a center to swing the pinchers on. The wire-cutter M is a piece ofsteel, either cast in the jaw or inserted afterward, and is placed backout of the way of articles to be grasped by the jaws, and close to thejoint, so that wire may be easily cut. The swage consists of asemi-conical tongue, H, fitting a depression of exact reversecounterpart in the other jaw. The two levers, with attachments, are castsolid, of anysuitable metal, and then riveted together, as shown at I.

To fit pipe, place jaws on the end of the pipe intended to go inside ofthe other length, so that the stop P will bear against the end; thenpress the jaws together, to crimp a corrugated pipe in as many places aswill reduce the pipe to the proper size.

The manner of using the other devices on the levers will be understoodfrom the drawing and foregoing description.

I have herein described the construction and use of the entire device,but confine the invention to the following claim.

I claim and desire to secure by Letters Patent of the United States- Thepivoted jaws Q It, provided with the swage H N and gage P, substantiallyas and for the purpose set forth.

- GEORGE H. STRONG.
